Tank Assembly problems of the 2003 BMW 325

Engine stalled in traffic; had to coast to side of the road. Would not re-start, despite strong cranking. Computer read "38 miles to empty" and gauge read approximately 1/4 to 1/8 tank of fuel remaining. Car was towed in and several faults were found: 240, 243. Dealer tech (vista BMW, FL) stated in service receipt: fuel sending units. Checked fuel pressure . . . Pressure was 3. 5 bar. Checked return fuel pressure at fuel tank . . . Pressure was 1. 0 bar. Removed both fuel sending units & performed resistance sweep of both resistance cars . . . Both left & right sending units had an open. Replaced left & right fuel sending units. Parts replaced: fuel sensor, suction unit. Safety consideration: sudden engine stopage can be extremely dangerous, yet this is not an isolated event. Internet web sites relate other BMW's with similar problems. Especially troublesome is the complete lack of warning. Please feel free to contact me if you would like additional information.
